The business of the novelist is not to relate great events, but to make small ones interesting -- Arthur SchopenhauerYour story idea could be as small as the events contained within an hour in time or could be about an insignificant event. You don't have to write about some great event in history to make your novel interesting. Instead, you need to write in an interesting manner about whatever event, large or small, you choose.
Here are three simple ways to make your story more interesting:
Create compelling characters with many layers.
Give your characters individual voices, so readers will identify their dialogue with them before even seeing a tag line.
Show the story through dialogue and action rather than telling it through all narration.
Pull in all the senses of the reader (sight, hearing, touch, smell, and taste) to pull the reader into the story.
Edit meticulously. If something isn't interesting to you, rewrite it.
